WITH regard to "Ted's Teaching Tips" (Friday, September 10), does Ted Wragg actually look at the photographs provided as the "teaching tip"? If so he may have questioned the concept of time-lapse photography in greater detail and asked the following:
Is there a difference between time-lapse and multiple exposure photography?
How did the photographer manage to ensure that the two people in the foreground would remain still while 200-plus aircraft approached Heathrow?
More importantly how did the photographer manage to keep the clouds still for that length of time?
Even Concorde managed to appear while some of the aircraft seemed to be in a dodgy approach pattern and all were below a suspiciously low cloudbase.
Couldn't the real answer have been that this was a photo montage, created by a Daily Mirror staff photographer to illustrate an emotive point, and not actuality?
A suspicious resource. Better stick to the literacy hour!

The picture was made by combining time-lapse photography with montage so that the planes captured on each exposure were inserted into the original scene to build a composite image.
